I Rely on My Family to Be Immortal and Live Forever

[Zu Zuo longevity system has been activated. Conditions for survival: The family bloodline is continuous. Reward: The host is free from aging forever and has endless lifespan. Warning: All clan members will die, and the host will die immediately. Once he traveled through time and became the young patriarch of a declining family on the border, Su Yan received a special gift of immortality. There is no need to meditate and practice hard, no need to risk one's life to hunt for treasure, but the price is to bear the fate of the entire family. Resources are scarce, the people's qualifications are mediocre, neighboring tribes are eyeing them, and crises are coming one after another. He is not obsessed with personal invincibility, but only concentrates on running the family business, training future generations, and resolving internal and external troubles. After a hundred years, the children become talented; after a thousand years of planning, the family rises. Countless old friends have been buried for years, but Su Yan stood quietly, watching the bloodline continue from generation to generation. The world thought that he was pursuing the path to immortality, but only Su Yan understood that his immortality was a shackle and gift in exchange for the lives of his entire clan.
